A tip for Crumar Stratus owners....and maybe others!

2007-01-18 by Eric Howard

My Strat sounded fine, but the power supply ran hot. I O-scoped it,
and several of the outputs were oscilating, more so when cold...
I changed some output caps, and added some more around the regs (78XX
likes caps to gnd on in and out-there were none installed!!)
 It does not seem to sound any different, but the  supply outputs are
stable now+it is BARELY even warm to the touch. If anything is going
to go bad with time, it's caps!
